Painful end-stage wrist arthritis unresponsive to conservative treatment is frequently managed with total wrist arthrodesis (TWA), which might render pain alleviation and ameliorate function, pain, and grip strength. Usual indications for TWA include inflammatory arthritis, idiopathic degenerative osteoarthritis (OA) and posttraumatic OA, Kienböck's illness, brachial plexus palsy, cerebral paralysis, infraclavicular brachial plexus blocks and other spastic and contracture base illnesses, scapholunate advanced collapse, scaphoid nonunion advanced collapse, and failure of other surgical techniques such as after failed total wrist arthroplasty, four-corner fusion, proximal row carpectomy and severe ligament injuries (this procedure is carried out when all other treatment alternatives have failed to control the individual's symptoms). TWA is commonly carried out with a dorsal plate fixed from the distal radius to the third metacarpal. However, other surgical procedures have been reported, including intramedullary fixation and new implants that do not cross the third carpometacarpal joint or some procedures without utilizing hardware for example using a vascularized fibular grafting In individuals with rheumatoid arthritis. TWA has been shown to give persistent and painless stability for 20 years or more. The rate of adverse events for TWA ranges from 0.1% to 6.1%, though some authors have published that it can be as high as 27%. The most common adverse events are tendon ruptures, peri-implant fractures of the third metacarpal, the need for hardware removal, and constant pain at the third carpometacarpal joint. In idiopathic degenerative OA, the reoperation rate following TWA has been reported as high as 63%. While TWA can render foreseeable pain alleviation and ameliorate function, orthopedic surgeons should remember that this surgical technique is not without its risks and that the accessibility of many surgical procedures requires orthopedic surgeons to scrupulously contemplate the risks and benefits of each alternative for the individual in front of them.

Pages 154-159BackgroundThe purpose of this analysis is to present a two-year follow-up of patient-reported outcomes, revision rate, and notable radiographic features of a convertible, diaphyseal-fit anatomic total shoulder arthroplasty system (ATSA).MethodsFrom June 2012 to June 2015, 100 shoulders were treated with ATSA using a convertible, diaphyseal-fit stem. Functional outcomes and radiographic findings were assessed preoperatively and at 6 months, 1 year, and 2 years postoperatively. Complications and reoperations were also determined.ResultsNinety-three shoulders were analyzed in this study. Patients were 47.3% male and had an average age of 67.3±8.1-years-old (range 44.7-89.1). Two-year clinical outcomes show a revision rate of 4.3%. Average preoperative ASES was 37.1±18.9 (6.7-86.7), SST (77.4%) was 3.1±2.4 yes responses (0-9), and SANE (88.2) was 25.4±21.5% (0-85.0%). At two years post-operative average (75% follow-up) ASES was 89.3±15.1 (37.0-100), SST was 10.0±2.5 yes responses (0-12), and SANE was 85.6%±17.0% (33.0-100%). Radiographic analysis at two years identified 2 shoulders (4%) with glenoid radiolucency (both Lazarus grade 1), 5 shoulders with at least one humeral radiolucent line (10%), and 9 shoulders (18%) with stress-shielding. There were 12 shoulders (24%) with distal pedestal formation. This finding was associated with the presence of radiolucent lines (P=0.002).ConclusionThis two-year analysis identified improvement in ASES, SST, and SANE scores and a low revision rate. presence presence of a distal pedestal was associated with increased rates of radiolucent lines. Further analysis with longer-term and more robust follow-up will improve our understanding of the risks and benefits of this shoulder system.Level of evidence: IIKeywords: Anatomic Total Shoulder Arthroplasty, Implant surveillance, Patient-reported outcomes, Revision Shoulder Arthroplasty, Total Shoulder Arthroplasty

Pages 160-165BackgroundAccurate analysis of preoperative shoulder pain and function is important for understanding treatment efficacy and producing high-quality research. Oftentimes, preoperative patient-reported outcomes (PROs) are missing. Therefore the accuracy of recalled preoperative PROs may be significant. We investigate the ability of patients who underwent rotator cuff repair (RCR) or shoulder arthroplasty (TSA) to recall their preoperative PROs.MethodsWe identified 145 patients who underwent either RCR or TSA and had preoperative PROs. All patients completed the ASES, SANE, SST, and VAS surveys within 3 months prior to surgery. Patients were contacted between one and four years after surgery and asked to recall their baseline pain and shoulder function prior to surgery. The mean difference was calculated by determining the difference between the mean recalled score and the mean actual score. Intraobserver reliability analysis was performed, comparing recall and actual score for each using the 2-way mixed-effects intraclass correlation coefficient (ICC) model. The ICC values > 0.75 were considered excellent, values between 0.4 and 0.75 were considered moderate, and values of < 0.4 demonstrated a weak agreement.ResultsFor patients who underwent RCR, the mean differences between actual and recalled ASES, SANE, SST and VAS pain were 6.3 (P=0.004), 2.0 (P=0.155), -0.04 (P=0.625) and - 1.0 (P<0.001), respectively. In patients who underwent TSA, the mean differences between actual and recalled ASES, SANE, SST and VAS pain were 4.5 (P =0.038), -3.9 (P=0.262), -1.2 (P=0.001) and -1.5 (P<0.001), respectively. ASES, SST, and VAS show moderate reliability, and SANE reliability was weak in both RCR and TSA populations. Patients had a tendency to recall higher pain scores than actual preoperative pain scores.ConclusionIn patients who underwent RCR or TSA, there was too much variability between individual patient’s ability to accurately recall preoperative pain and function to reliably use recall data for research purposes.

Pages 166-172ObjectivesTraditionally used to treat rotator cuff tear arthropathy (CTA), reverse total shoulder arthroplasty (RTSA) is becoming increasingly utilized for the treatment of proximal humeral fractures (PHF). The purpose of this study was to use a matched cohort analysis to assess differences in 90 -day complications as well as 2-year and 5-year implant survival between patients undergoing RTSA for CTA and patients undergoing RTSA for PHF.MethodsPatients with at least a 5-year follow-up who underwent primary RTSA for either PHF or CTA were identified in a national database (PearlDiver Technologies) using current procedural terminology (CPT) and international classification of diseases (ICD) 9 and 10 codes. Patients with a surgical indication of PHF were matched with patients with a surgical indication of CTA based on age, sex, Charlson Comorbidity Index, smoking status, and obesity (body mass index (BMI)>30). All-cause revision at the 2-year and 5-year postoperative time intervals were assessed. Reimbursements for the surgical care episode up to the 30-day, 90-day, and 1-year postoperative intervals were also assessed. Bivariate analysis was performed with a significance set at P<0.05.ResultsIn total, 802 PHF patients were matched with 802 CTA patients. Compared to CTA patients, PHF patients undergoing RTSA were significantly at increased risk of atrial fibrillation, anemia, and heart failure within 90 days of surgery. Notably, there was no significant difference in all-cause revision surgery at 2-year and 5-year postoperative intervals or hospital reimbursements at the 30-day, 90-day, and 1-year postoperative intervals.ConclusionPreoperative indication appears to be an important driver of healthcare utilization for RTSA, as PHF patients undergoing RTSA have a higher risk of short-term postoperative complications compared to CTA patients. However, there is no difference in hospital reimbursement for the two indications of RTSA, suggesting that current payment modalities may not appropriately adjust for risk based on the surgical indication.

Pages 173-179ObjectivesThis study aimed to evaluate the effect of hypoalbuminemia on failure rates and mortality after a two-stage revision for PJI.Methods199 Patients (130 knees and 69 hips) with a mean age of 64.7 ± 10.7 years who underwent a two-stage exchange were retrospectively reviewed at a mean of 51.2 ± 39.7 months. Failure of treatment was defined as any revision within the follow-up period, failure to undergo reimplantation, or death within one year of initiating treatment.ResultsThere were 71 failures (35.7%), including 38 septic failures (19.1%). We found no differences between successful revisions and failures regarding hypoalbuminemia (43% vs. 42% prior to stage 1, P=1 and 32% vs. 29% prior to stage 2, P=0.856). There were also no differences in hypoalbuminemia rates between septic failures and the rest of the cohort (42% vs. 43% prior to stage 1, P=1.0 and 34% vs. 30% prior to stage 2, P=0.674). Hypoalbuminemia prior to stage 2 was a significant predictor of mortality based on multivariate analysis (odds ratio 5.40, CI 1.19-24.54, P=0.029). Hypoalbuminemia was independently associated with a greater length of stay by 2.2 days after stage 1 (P=0.002) and by 1.0 days after the second stage reimplantation (P=0.004).ConclusionPreoperative hypoalbuminemia is a significant predictor of mortality and increased length of stay following two-stage revision but is not a predictor of failure of PJI treatment. Further study is required to understand if hypoalbuminemia is a modifiable risk factor or a marker for poor outcomes.Level of evidence: IIIKeywords: Albumin, Hypoalbuminemia, Periprosthetic joint infection, Two-stage

Distal Femoral Valgus Resection Angle in Conventional Total Knee Arthroplasty - a CT Scanogram StudyPages 180-187ObjectivesIn conventional total knee arthroplasty (TKA), the distal femur valgus resection angle (DFVA) is decided either by measuring the specific resection angle for each patient on preoperative anteroposterior hip-knee-ankle (HKA) weight-bearing radiograph or using a fixed resection angle of five to seven degrees, when such facilities are not available. This study aims to measure the DVFA in TKA patients using preoperative HKA non-weight-bearing computerized tomography (CT) scanogram scout films and determine its relation with preoperative coronal plane lower-limb deformities.MethodsIn this retrospective radiological study, various measurements were performed on bilateral, preoperative hip-knee-ankle CT scanograms of 73 knee osteoarthritis patients who had presented for total knee replacement surgery using a standard protocol. The angle between the femoral anatomical axis and femoral mechanical axis was measured as the femoral mechanical anatomical angle (FMAA), which corresponds to the surgical DFVA. The angle between the femoral and tibial mechanical axes was measured as mechanical femorotibial angle (MFTA). The correlation between FMAA and MFTA was studied.ResultsThe mean FMAA for the study group was 6.45° (range 3° to 11°, SD 1.17°). The MFTA for the study group ranged from 24° varus to 14° valgus. The alignment was valgus in 14.4% (n=21), varus in 84.2% (n=123), and “0 degrees” in 1.3% (n=2). With valgus coronal alignment taken as positive and varus as negative, the Pearson's correlation coefficient for MFTA with FMAA was r = −0.5183 (p<0.001), indicating that valgus knees tended to have a smaller FMA angle and varus knees tended to have a larger FMA angle.ConclusionIn the non-availability of individualized measurements, in primary TKA, we recommend setting DFVA as five degrees for valgus deformities, six degrees for mild/moderate varus deformities (MFTA <15°) and seven degrees for severe varus deformities (MFTA > 15°).

Pages 188-196Objectives
Perioperative dexamethasone is an effective anti-emetic and systemic analgesic in total hip arthroplasty (THA) that may reduce opioid consumption and enhance rapid recovery. However, there is no consensus on the optimal perioperative dosing that is safe and effective for faster rehabilitation and improved pain control while maintaining safe blood glucose levels.
MethodsA retrospective review of 101 primary THA patients at a single institution who received perioperative dexamethasone was conducted. Patients were stratified by dexamethasone induction dosage (10 mg as high, <6mg as low) and whether a repeat dose was given 16-24 hours postoperatively. Age, gender, BMI, diabetes status, and ASA were controlled between groups. The pain was evaluated with inpatient morphine milligram equivalents (MME) requirements and visual analog scale (VAS) at 8, 16, and 24 hours postoperatively. Mobility was assessed by inpatient ambulation distance, Boston AM-PAC mobility score, and percentage of gait assistance as determined by a physical therapist. Secondary outcomes included postoperative nausea and vomiting (PONV) limiting therapy sessions, PONV requiring breakthrough anti-emetics, glucose levels, surgical site infection, wound healing complications, and discharge destination.
ResultsCompared to patients receiving one dose of high or low dexamethasone, patients receiving two dosages of high-dose dexamethasone had significantly further ambulation distance and lower percentage of gait assistance on postoperative day 2. A generalized linear model also predicted that any repeat dexamethasone, regardless of dosage, significantly improved ambulation distance and gait assistance compared to the one-dose cohort. There was no statistically significant difference between VAS scores, MME requirements, PONV, postoperative glucose levels >200, discharge destination, or risk of infection between groups.
ConclusionA repeat high-dose dexamethasone, the morning after surgery, may improve percentage of gait assistance and ambulation endurance on postoperative day two. There was no risk of uncontrolled glucose levels or infections compared to receiving one dose of dexamethasone at induction. Level of evidence: III

Pages 197-205BackgroundDevelopmental dysplasia of the hip (DDH) is a condition with variation among ethnicities and regions. We aimed to investigate the effect of a gestational week of birth on the sonographic acetabular hip angles of newborns.MethodsWe prospectively scanned the hips of neonates born in a single, tertiary hospital during their first week of life, using the Graf sonographic method. Demographics, obstetric history of the mother, birth weight, parity, presentation, family history of developmental dysplasia of the hip (DDH), gender, mode of delivery, single/multiple birth, and gestational age were recorded. Acetabular α and β angles were measured, and hip type was determined according to Graf’s classification. Patients were divided according to the gestational age of birth (<37 weeks, 37-38, 38-39, 39-40, >40 weeks).ResultsFrom May- October 2020, 342 babies (684 hips) were examined (52.9% males / 47.1% females). 76.7% were Caucasian-Greek, and 88.3% were term babies. There was a significant difference between the α-angles of the right and left hip in both genders. More females had Type II hips than males. Subgroup analysis did not reveal a significant difference in hip angles of term babies. There was no correlation between birth weight or gestational age and hip angles. Female gender and the existence of maternal thyroidopathy were positively correlated with Type II hips.ConclusionGestational birth age in term infants is unimportant regarding acetabular hip angles. Female gender and maternal thyroidopathy appeared to be related to hip type. Further investigation may be warranted to elucidate the effect of maternal thyroidopathy and hip development.

Pages 206-211BackgroundTo evaluate patients with chronic ankle instability (CAI), copers who had a sprain without instability, and healthy controls using the Star Excursion Balance Test (SEBT). In addition, the reach distance was assessed between the both legs in terms of dominant and non-dominant in all groups.MethodsA total of 75 subjects (25 healthy, 25 CAI, and 25 Coper) participated. The maximum reach distance in SEBT was assessed in anterior (ANT), postero-medial (PM), and postero-lateral (PL) directions in both legs for each subject. All data were analyzed by SPSS version 21. Tukey post hoc test was used to compare all groups. Paired T-test was used to compare dominant and non-dominant legs in each group.ResultsIn 75 subjects have participated in the data collection, no significant differences were reported among all groups for age and BMI measurements. Significant lower reach distance in scores of ANT in the dominant leg of the CAI was demonstrated when compared with the control and the coper groups (P=0.008). No statistical significant difference was determined between the dominant and non-dominant legs in each group (P>0.05).ConclusionIt seems that relevant strategies for postural control should be taken into account in the rehabilitation setup of individuals with CAI.Level of evidence: IIKeywords: Ankle, Balance, dynamic, Postural control, Postural stability, sprain, star excursion balance test

Pages 212-217ObjectivesSport is one of the best ways to prevent osteoporosis; however, not all sports have the same impact on bones, for instance, swimming (SW) may have no effect or be harmful. Elite athletes are the best choice to detect the effects of any sport. Thus, this study was conducted firstly to compare the bone mineral density (BMD) and bone mineral content (BMC) of elite athletes in vol leyball (VB), basketball (BB), and long-distance running (LR) together, and secondly to compare those corresponding values in SW athletes with those of non-athletes (NA).MethodsThe subjects (n=58) of this cross-sectional study included elite male athletes (members of Iran's national teams, with a minimum of 12-15 hours of training per week) and NA (control; C) who were divided into BB, VB, LR, SW (n=12 for each), and C (n=10) groups. The DEXA scan measured the amount of BMD and BMC values in the lumbar spine (LS; L2-L4) and proximal femur (PF; neck, trochanter, and Ward’s triangle) areas.ResultsIn the LS areas, LR had significantly higher BMD than the BB, VB, SW, and C groups (P<0.001), while for BMC, both LR and VB were significantly superior to other groups (P<0.001). Moreover, the BMD and BMC of the PF areas of VB and BB were significantly higher than those of the LR, SW, and C groups (P<0.001). Finally, in all areas, SW showed significantly higher BMD and BMC, compared to the C group (except for trochanter and femur neck BMC) (P<0.05).ConclusionLR athletes showed the most bone acquisition in the LS areas and VB players in the PF areas, while BB players ranked third in osteoporosis prevention in the mentioned regions. Unexpectedly, SW athletes also had better BMD and BMC than NA; therefore, after weight-bearing sports, this type of sport can be effective in bone acquisition.

Pages 218-224ObjectivesTo investigate the incidence and severity of knee pain following retrograde intramedullary nailing offemur fractures and to better understand functional outcomes using validated patient-reported outcome measures.MethodsFifty-three patients with OTA 32 or 33 fractures treated by retrograde nail at a single academic Level 1 trauma center between 2009 and 2020 were retrospectively reviewed. Patients verbally completed the Oxford Knee Score (OKS) and Patient-Reported Outcome Measurement Information System (PROMIS) Short Form 6b, minimum one year postoperatively.ResultsThirty-four (64%) patients reported the presence of pain. Of those reporting pain, 16 (47.1%) reported their pain as mild. Compared to those without pain, patients with knee pain had lower OKS (30.38 +/- 10.65, versus 41.95 +/- 6.87; P <0.001) and higher PROMIS scores (14.65 +/- 6.76 versus 10.95 +/- 7.09; P=0.066).ConclusionThe increasing severity of pain was inversely correlated with functional status as measured by patientreported measures. At present, the reliability, high union rates, and otherwise low complication rates associated with retrograde femoral nailing justify its continued use. However, knee pain and functional outcomes should remain an integral part of the preoperative discussion with the patient.
